Pinpoint Test Z: The Anti-Theft Indicator Is Never/Always On

Normal Operation

The Instrument Panel Cluster (IPC) interacts with the PCM (non-hybrid) or Transmission Control Module (TCM) (hybrid) and controls the Passive Anti-Theft System (PATS) function. The IPC controls the anti-theft indicator based upon the status of the PATS.

The anti-theft indicator proves out for 3 seconds when the key is turned to the ON or START position. If there is a PATS concern, the anti-theft indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the ignition is switched to the ON or START mode. The PATS also flashes the anti-theft indicator every 2 seconds at ignition off to act as a visual theft deterrent for all vehicles.

This pinpoint test is intended to diagnose the following:

- PATS concern
- IPC



PINPOINT TEST Z: THE ANTI-THEFT INDICATOR IS NEVER/ALWAYS ON

-------------------------------------------------
Z1 CHECK THE ANTI-THEFT INDICATOR OPERATION


- Ignition ON.
- On early build vehicles, enter the IPC dealer test mode.
- Scroll through the displays to TELLTALE TEST and monitor the anti-theft indicator.
- Enter the following diagnostic mode on the scan tool: IPC DataLogger (Late Build) .
- On late build vehicles, select the IPC anti-theft indicator (THEFT_LMP) active command. Command the anti-theft indicator on and off while observing the anti-theft indicator.
- Does the anti-theft indicator illuminate when commanded on through DataLogger (late build) or through the dealer test mode (early build), and turn off when commanded off through DataLogger (late build) or through the dealer test mode (early build)?

Yes
GO to Z2.

No
INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) Instrument Panel Cluster (IPC). TEST the system for normal operation.

-------------------------------------------------
Z2 RETRIEVE THE RECORDED DTCs FROM THE CONTINUOUS IPC SELF-TEST


- Check for recorded IPC DTCs from the continuous self-test.
- Are any PATS-related DTCs recorded?

Yes
REFER to Antitheft and Alarm Systems.

No
INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) Instrument Panel Cluster (IPC). TEST the system for normal operation.
